Picture the havoc a dozen such vultures could create attacking a city like London or Paris. Present-day defense against these ships is totally inadequate. In attacking large places, the Zeppelins would rise to a height of from 6,000 to 8,000 feet, at which distance these huge cigar-shaped engines of death, 700 feet long, would appear the size of a football, and no bigger. I know that Zeppelins have successfully sailed aloft at an altitude of 10,000 feet. Picture them at that elevation, everybody aboard in warm, comfortable quarters, ready to drop explosives to the ground. The half informed man--and there appear to be many such in European cabinets, which recalls the proverb about a little knowledge being a dangerous thing--likes to say that a flock of aëroplanes can put a dirigible out of business. Consider now an aëroplane at an elevation of 6,000 feet and remember that the new Zeppelins have gone thousands of feet higher. An aviator at 6,000 feet is so cold that he is practically useless for anything but guiding his machine. How in the world is he or his seat-mate going to do harm to a big craft the size of the Zeppelin that is far above him? An aviator who has ever gone up, say 8,000 feet, will tell you when he comes down what a harrowing experience he has had. What good can an individual be, exposed to the temperature and the elements at such an altitude, in doing harm to the calm, comfortable gentlemen in the heated compartments of the Zeppelin?--Quatsch! which is a German army term for piffle! At 8,000 feet the small target a Zeppelin affords would move at a rate of speed of from thirty-five to sixty miles an hour. The possible chances of being hit by terrestrial gunfire are infinitesimally small. This does not take into account the vast opportunities that a dirigible has for night attacks or the possibility of hiding among the clouds. The X 15, sailing over London, could drop explosives down and create terrible havoc. They don't have to aim. They are not like aviators trying to drop a bomb on the deck of a warship. They simply dump overboard some of the new explosive of the German Government, these new chemicals having the property of setting on fire anything that they hit, and they sail on. They do not have to worry about hitting the mark. Consider the size of their target. They are simply throwing something at the City of London. If they do not hit Buckingham Palace they are apt to hit Knightsbridge. And remember that whatever one of the new German explosives strikes, conflagration begins.
